Processes That Change Earth

What is weathering?

• When Earth material, like rock, sand, and soil are being carried away from their original location
• When Earth materials are broken down into smaller pieces
• When Earth materials, like rock, sand, and soil, are dropped or deposited into a new location.
• When the Earth changes quickly and it looks different from before.

What is erosion?

• When Earth materials, like rock, sand, and soil are being carried away from their original location
• When Earth materials are broke down into smaller pieces
• When Earth materials, like rock, sand, and soil, are dropped or deposited into a new location
• When the Earth changes quickly and it looks different from before

What process does the picture demonstrate?

• a flood
• weathering
• erosion
• deposition

What do all of these words have in common? landslide, flood, earthquake, volcanic eruption

• They are all rapid processes
• They are all slow processes
• They are all landforms
• They are all water features

Which rapid process occurs when the plates of Earth shift rapidly and the surface of the ground shakes and rolls causing damage to Earth's surface, like cracks, and other openings, and damage to roads and buildings?

• landslide
• earthquake
• flood
• volcanic eruptions

What is deposition?

• When Earth materials, like rock, sand, and soil are being carried away from their original location.
• When Earth materials are broken down into smaller pieces.
• When Earth materials like rock, sand, and soil, are dropped or deposited into a new location.
• When the Earth changes quickly and it looks different from before.

Which of the following describes how a volcanic eruption changes Earth?

• It can cause cracks on the surface of Earth and destroy buildings.
• It can make a volcano larger and add new rocks to the Earth's surface
• It can carry away parts of the Earth and drop them to lower locations.
• It can create valleys and canyons by taking away the Earth a little at a time

What event can cause most landslides?

• Too much rain soaking the ground of a mountain and making the soil loose.
• Too much shaking of the Earth's water
• Too much lava coming out of a volcano during an eruption
• Too much wind blowing the side of a mountain.

Which of the following is in the picture?

• volcanic eruption
• landslide
• weathering of the rocks
• flood

What most likely happened to the land in the picture?

• A volcanic eruption has built up the land
• Soil has been deposited on the sides of the river
• People have dug up the ground around the river
• The river has weathered and eroded the earth material away
